Title:
マルチユーザ直交周波数分割多元接続をオプトインおよびオプトアウトするためのスイッチングスキーム
Document Type and Number:
Japanese Patent JP7300557
Kind Code:
B2
Abstract:
This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.
